Here's my take on what at least part of 2nd MarDiv was up to during the Summer 2000 offensive.

Incidentally, canon has the 2nd MarDiv start (per the U.S. Army Vehicle Guide) and end (per Going Home) in the same city. Furthermore, Going Home mentions that 2nd MarDiv ended up stronger and more diverse after the offensive. No explanation for this is given, however.
